Not sure if chemicals were dumped into river. Was shutdown as a safety precaution since many barges are heated.

Will remain shutdown until they get the OK from local emergency crews.

Hamilton and Harrison say things are moving better and quicker than expected..hope to turn it over to contractor for cleanup/containment soon -believe the butadiene has sealed itself off so while it may still be leaking..slower and less than before -still a threat but it's substantially less than before
